The hair mods, or all of them?
If it is the hair mods, remember Mesh quality has to be on Ultra and that they do not show up in the Black Emporium mirror(No idea why, but they don't).
And I have to ask, did you merge the files and put the mods into the correct folder in the Mod Manager thingie?
[EDIT] Also, do not use the Nexus manager, get the one from the forum, the alpha one, that's the one you want.
I only have hair mods atm, but they don't show up anywhere, not even at the CC at the beginning of the game, and yes, I have mesh quality on ultra, I even tried setting everything on ultra and still no mods visible.
I downloaded this mod manager: http://www.nexusmods...tion/mods/116/?(DAI ModManager v0.48 alpha)
and I followed every step:
1/ Make sure to set up a central mod directory somewhere on your PC, where you place all your mods, distributable mods need to be placed in their own unique directories, inside these should be the package.mft file. DAIMOD mods can be placed anywhere in the central directory. Please refer to the screenshot below

2/ Launch the DAI Mod Manager tool, you should be prompted to select your Dragon Age Inqusition executable (This is not the mod manager executable). This is to establish the base path of Dragon Age to look for patch related files during patching. If for whatever reason you are not prompted, you then have the option to choose the directory once the tool loads, just hit browse next to the Dragon Age Path textbox.
3/ Next choose your central mods directory you created earlier (You do not select each individual mod folder, as this will clear out the mods list each time). If you select the right directory, you will see the mods list populate with all available mods.

4/ Select the mods you wish to install. For the new DAIMOD format, there is a configure button in the mod description area. If it is clickable, it means the mod has configurable parameters, click on it to bring up the parameters to configure. (Right now this feature is very very new, it will eventually become more powerful, flexible, and prettier).
5/ Prior to launching, review the options.
5a/ Verbose Logging - This will list every action that is taking place, for every bundle, you only ever need to turn this on if you are asked to, for debugging purposes, as it will tell me exactly where the process stopped.
5b/ Force rescan of Patch - In this version of the Mod Manager, the patch is deconstructed into a series of actions and cached for later reuse, if for some reason the patch is not being applied correctly, you can mark the cache for reconstruction.
6/ Finally hit merge, you then are given the choice to pick your output directory, you can either save it to somewhere on your PC outside of the DA directory and then copy it in afterwards or save it to the Update directory (under its own unique directory ie. Merged). If you try to save it to the base of the Dragon Age directory, the base of the Update directory, or try to overwrite your patch, you will recieve a message box prompting you to reread the instructions.

7/ If all went well you will see a new window popup, giving you feedback on the process. If this is the first time you have run this version of the tool (or a later version) or if a new patch has been released by Bioware, then it will begin by processing the patch - This is the deconstruction process, it can take anywhere from 5 - 10 minutes to complete, after which it is cached, and further merges will not take nearly as long.

8/ When the process completes, if you saved the merged patch elsewhere, then copy to the Dragon Age Update directory, then launch the game and enjoy.
maybe the version of the DAI MM I'm using is too old?
note: I also installed this: http://www.reddit.co...leased_patch_7/
because the DAI MM previously encountered an error when merging the package and prompted the following message: "Task failed. Error reported was: Object reference not set to an instance of an object."
